MTA Exploratory is a lightning fast testing tool by Menditect that connects AI testing assistants directly to a local Mendix runtime using the Model Context Protocol (MCP).
It allows Mendix developers and testers to test microflow logic and edge cases locally in real time with automatic database rollbacks, and instantly promote those exploratory tests into permanent automated MTA regression test suites using a simple prompt.
Explore boundary conditions instantly while coding, keep your database pristine with automatic rollback, and promote tests into permanent regression suites with a single prompt.
Testing Mendix business logic during active development no longer requires slow browser clicking or cluttered databases. MTA Exploratory connects your AI coding assistant directly to your local Mendix runtime via the open Model Context Protocol (MCP) standard.
Execute complete test matrices in milliseconds, verify edge cases in-memory, and seamlessly promote passing tests into permanent, automated MTA test suites.

Never throw away what you just tested!
The best part of exploratory testing is that your testing effort is never thrown away. Once you verify your microflow logic and all boundary scenarios pass, you can turn your exploratory test into a permanent regression asset with a single prompt:
“Promote this exploratory test into a permanent MTA test suite.”

Unifying AI coding assistants, Mendix Model discovery, and MTA via the Model Context Protocol (MCP)
MTA Exploratory fits naturally into your existing editor—whether you work in Mendix MAIA, Cursor, Claude Code, GitHub Copilot, Gemini / Antigravity, or Windsurf. It operates across four decoupled layers:
mxcli / Studio Pro MCP): The assistant inspects the compiled visual Mendix model (.mpr) directly. If user stories or documentation are missing or outdated, the visual model serves as the single source of truth./plugin/mcp): Embedded directly in your local Mendix application, enabling instant in-memory test execution via the execute-testcase tool./primitivetools/mcp): Connects to your central MTA platform to author, organize, and execute permanent regression suites.Simply prompt your assistant: “Test the calculateDiscount microflow with standard, bulk, and VIP customer scenarios.” Within seconds, results and timings appear directly in your IDE.

No more manual test data entry
Use a prompt to generate test data in your database without manual test data entry or writing microflows to generate data. With the knowledge of the Mendix model, the reasoning capabilities of your AI agent and the execution of the MTA plugin, you can create realistic test data for manual testing your app.

Why waiting for redeploys and clicking through forms slows down Mendix development
Mendix allows developers to build data models, complex calculation microflows, and user interfaces in record time. But checking whether a microflow handles all edge cases correctly has traditionally created a frustrating dilemma:
With MTA Exploratory, you no longer have to choose between quick local checks and repeatable regression suites.
